What are your exact light_environment settings? If you want to set a night-time environment, the light setting should probably be around 25-50. Ambient is the amount of "scattered light" that comes from any skybox texture. It has no particular direction but exudes light perpendicular to any skybox texture surface. [addsig]

In the real world, even when sunlight is not coming directly into a room, there is still plenty of light during the daytime, correct? That's scattered light. It comes through the windows even though no direct light shines into the room.

Set the brightness to 50 instead of 200. What color is 229 229 229? Change ambient brightness to 10 instead of 20.

kdhunt, please start putting some effort into spelling. It looks like either your sun is too bright (the last of 4 values in the brighness field) or that you need cubemaps.

Just a guess, have you tried placing an [e]env_cubemap[/e] in your map and then to call the 'buildcubemaps' command from the console after the map has loaded? [addsig]

for night time you need to make a white-blue color light_environment.

 000 000 000 200 < this is the brightness

        |----------|this is the color


make an env_cubemap in your map above the water, then once your in game run the console command buildcubemaps.

try a diffrent water or sand texture and see if that helps.

Valve explains in the source sdk documentation that 'Using the cubemap as a sampling point, specular and environment-mapped materials are able to more accurately reflect their environments' read more about this at:
